OK SV gang, lets hear your thoughts / reasons why the non vented optispark distributor are the cause of so much pain and agony in the C4 community. I'm soon to be on my third opti. The two aftermarket optis that I've installed on my 94 coupe were modified to vent, but this appeared not to have prolong their life on my DD as I was lead to believe. One lasted almost a year and the 2'nd last less than 6 months.. Sensor problems appear to be the main culprit by what little research I've done on the internet. Neither of the opti that I've install or remove showed any signs of moisture being the causing of failure!! So lets hear it!! What do we do other than sell the car.. Who has had long term success and with who's opti..
